RE: strange error when sending dataset using WSE 2.0 encryption

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

I found the bug in .NET Framework Assembly System.Data.dll

Declaring Type: System.Data.XmlTreeGen
Assembly: System.Data, Version=1.0.5000.0

method

private void GenerateConstraintNames(DataTable table)
{
foreach (Constraint constraint1 in table.Constraints)
{
string text1 = constraint1.ConstraintName;
for (int num1 = 0; this.ConstraintNames.Contains(text1); num1++)
{
text1 = table.TableName + '_' + constraint1.ConstraintName;
if (num1 > 0)
{
text1 = text1 + '_' + num1.ToString();
}
}
this.ConstraintNames.Add(text1);
constraint1.SchemaName = text1;
}
}
