Compile time Error for Passing value from a TextBox to RDLC report

I want to pass a textbox value to RDLC report. For said purpose my code is:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Microsoft.Reporting.WebForms;
using System.IO;
using System.Data.SqlClient;
using System.Configuration;
using System.Globalization;
ReportParameterCollection reportParameters = new ReportParameterCollection();
reportParameters.Add(new ReportParameter("ReportParameter1", t1.Text));
this.reportViewer2.LocalReport.SetParameters(reportParameters);
this.reportViewer2.RefreshReport();
But i get the error during compile time which is:
Error 15 The best overloaded method match for 'Microsoft.Reporting.WinForms.Report.SetParameters(System.Collections.Generic.IEnumerable<Microsoft.Reporting.WinForms.ReportParameter>)' has some invalid arguments
Error 16 Argument 1: cannot convert from 'Microsoft.Reporting.WebForms.ReportParameterCollection' to 'System.Collections.Generic.IEnumerable<Microsoft.Reporting.WinForms.ReportParameter>'
This error occurs on following line:
this.reportViewer2.LocalReport.SetParameters(reportParameters);
Help is required to resolve it. Thanks in advance

I resolved the error by replacing Microsoft.Reporting.WebForms with Microsoft.Reporting.WinForms

Cannot find the namespace for generic type "List"

I have a strange error and don't know how to solve that. I have a Form which gets opened by another (Main)Form. When I write
List<String> valStoreAsString = new List<String>();
I get "The value or namespace List could not get found". My using directives are the following:
using System;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Data.SqlClient;
using System.Collections;
using System.Runtime.InteropServices;
In the other Forms it works fine. What happened here?

Add following using directive to the list of usings.
using System.Collections.Generic;
Tip
If you are using Visual Studio and if you don't know the namespace then type name of type (Case sensetive) in editor and then press ctrl+ . and select add using option and VS will add related using for you.
or you can right click on name of Type and select Resolve option and select using .... sub option.

c# ProcessMemoryReaderLib not working

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
using ProcessMemoryReaderLib;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
This seems to always return the error
"Error 1 The type or namespace name 'ProcessMemoryReaderLib' could not be found (are you missing a using directive or an assembly reference?) C:\Users\giacomo\documents\visual studio 2010\Projects\WindowsFormsApplication1\WindowsFormsApplication1\Form1.cs 10 7 WindowsFormsApplication1
"

In your Solution Explorer, right click your References > Add Reference then click Browse, then find and select your .dll File and add it to your references. You can't include a library in your project with using if you don't include your assembly.
Take a look at here for more details: http://msdn.microsoft.com/en-us/library/wkze6zky.aspx

Just build the project after adding the reference of the ProcessMemoryReaderLib.dll in your project,then use using ProcessMemoryReaderLib; in your class file

I can't see RenderMode-property in ToolStripSeparator c#

I have a problem with RenderMode-property of the ToolStripSeparator.
When I put the following line of code :
this.toolStripSeparator1.RenderMode = ToolStripRenderMode.System;
I have the following error :
error 44 'System.Windows.Forms.ToolStripSeparator' does not contain a
definition for 'RenderMode' and no extension method 'RenderMode'
accepting a first argument of type
'System.Windows.Forms.ToolStripSeparator' could be found (are you
missing a using directive or an assembly reference?)
Despite, I put the references
using System.Windows.Forms;
Below is a list of my references
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Threading;
using System.Diagnostics;
Do you have any ideas what could cause this error?

ToolStripRenderMode Enumeration's value can be assigned to RenderMode property of ToolStrip.
ToolStripSeparator donot have any such property.
I think you should use it like this:
toolStrip1.RenderMode=ToolStripRenderMode.System;

namespace name 'DispatcherTimer' could not be found

I am trying to use a dispatch timer, but my c# app can't find the namespace. This is the error:
The type or namespace name 'DispatcherTimer' could not be found (are you missing a using directive or an assembly reference?)
Here is what I am using:
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.SqlClient;
using System.Globalization;
using System.Text;
using System.Threading;
using System.Timers;
using System.Windows.Forms;
Here is the code:
DispatcherTimer timer1 = new DispatcherTimer();

DispatcherTimer is not a namespace - it's a class within the System.Windows.Threading namespace and the WindowsBase assembly. So you need
using System.Windows.Threading;
In general, a search for the missing type name and "MSDN" is enough to find out where to find a type.

The Dispatcher class is in WindowsBase.dll. You MUST add that reference to your project to use "using System.Windows.Threading;" <>

Add this using:
using System.Windows.Threading;
MSDN

Isn't in the System.Windows.Threading namespace and not the System.Threading namespace?
http://msdn.microsoft.com/en-us/library/system.windows.threading.dispatchertimer.aspx

You must Add WindowsBase in your references so you can use the System.Windows.Threading.
