Hi,

I am calling a GetSerialNo function But it showing some error like:

Cannot implicitly convert type 'decimal' to 'int'. An explicit conversion exists (are you missing a cast?).

Can anyone help me to solve this issue.

Here is the code:

int slNo= GetSerailNo(keydata);



private int GetSerailNo(String keydata)
	{
        
        SqlConnection con = new SqlConnection(@"server=Servername;database=DBNAME;uid=Username;pwd=Pwd;max pool size=250;Connect Timeout=0");
        con.Open();
		cmd = new SqlCommand("select isnull(max(slno)+1,1) from d001docs where source_keydata='" + keydata + "'", con);
		dynamic no = cmd.ExecuteScalar();
		cmd.Dispose();
		con.Close();
		return no;
	}</pre>

Thanks in advance

Solution 1

It means what it says. Your code is passing a decimal where an int is expected. You need to explicitly cast it, with Convert.ToInt(), I guess. I assume the issue is your return type, why not just change it ? Also, buy a C# book and read it, the error messages don't get any clearer than this one.

Solution 2

no is decimal while your function return value is int, hence the error (decimal datatype is wider than int) you may either:

Change your function (and your slNo variable) data type to decimal.

or

Explicitely cast no to int:
```
return (int) no;
```
(warning: use this technique only if you are sure the values will always fit into int range).
