Too many characters in character literal

An attempt was made to initialize a char constant with more than one character.

CS1012 can also occur when doing data binding. For example the following line will give an error:

<%# DataBinder.Eval(Container.DataItem, 'doctitle') %>

Try the following line instead:

<%# DataBinder.Eval(Container.DataItem, "doctitle") %>

The following sample generates CS1012:

// CS1012.cs  
class Sample  
{  
   static void Main()  
   {  
      char a = 'xx';   // CS1012  
      char a2 = 'x';   // OK  
      System.Console.WriteLine(a2);  
   }  
}

Sashaa_i, строки в C# должны быть в двойных кавычках. Одинарные кавычки используются для символов.

I am trying to create a string in a javascript function to resolve path for an image handler url, but I am getting the following error:

Compiler Error Message: CS1012: Too many characters in character literal

The Javascript function code is given in the Code section. The following line is highlighted red as the error:

var ImageUrlPath = <%= sting.format(‘PicHandler.ashx?Src={0}&ImgId={1}&CallingSource={2}&maxHeight={3}&maxWidth={4}, «HWDetails»,’ + HImgID.ClientID + ‘, «EnlargedImage»,’ + 600 + ‘,’ + 600 + ‘;’ ) %>

Please help me fix error in this line.

function ChangeCursor()
    {
        this.className ='linkClassPointer';
       var control = document.getElementById('<% =HPost.ClientID %>').value;
        alert (control);
        
        if ((control==null) || (control=="") || (control.length==0))
             var x=1
        else
        {
            alert(control);
            var ImageRightPaneID=document.getElementById('<% =ImageRightPane.ClientID%>');
            var imgID = document.getElementById('<% =HImgID.ClientID %>').value;
            
            var ImageUrlPath = <%= sting.format('PicHandler.ashx?Src={0}&ImgId={1}&CallingSource={2}&maxHeight={3}&maxWidth={4}, "HWDetails",' + HImgID.ClientID + ', "EnlargedImage",' + 600 + ',' + 600 + ';' ) %>
            var imageSrc = <%= ResolveClientUrl(ImageRightPane.ImageUrl) %>; 
            
            
            ImageRightPaneID.onclick = "ImageRightPaneID.src='" + ImageSrc + "'";
 
           
            
                                   
            }

Hello! I would like to know how to fix this error and what it means I am writing for the first time. And I’m new to C#

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class NewBehaviourScript : MonoBehaviour
{
    public float speed;
    private Rigidbody rb;
    float MoveHorizontal;
    float MoveVertical;

    void Start()
    {
        rb = GetComponent<RigidBody>();
    }


    void FixedUpdate()
    {
        Vector3 movement = new Vector3(MoveHorizontal, 0.0f, MoveVertical);

        rb.AddForce(movement * speed);
    }

    public void Up()
    {
        MoveVertical = 1f;
    }

    public void Down()
    {
        MoveVertical = -1f;
    }

    public void StopMoveVertical()
    {
        MoveVertical = of;
    }

    public void Left()
    {
        MoveVertical = 1f;
    }

    public void Right()
    {
        MoveHorizontal = -1f;
    }

    public void StopMoveHorizontal()
    {
        MoveHorizontal = 'of';
    }
}

In C#, strings are put between double quotes ("), not single quotes ('). The compiler is telling you that you are trying to put too many characters into a single character. There are special cases where you can use multiple characters to denote a single special characters. Ex. 't' for a Tab character.

Once you get past that problem, you’ll run into the problem of trying to assign a string to a float. C# is a strongly typed language. Variables (except dynamic variables) have a single specific type. You can only assign values of that type to that variable.
